In competitive Pokemon Chansey is really damn bulky, especially with Eviolite... It has a plethora of annoying moves such as Soft-Boiled, Heal Bell, Stealth Rock, Thunder Wave, and other stuff along the lines of that... Don't get me wrong, Chansey is a fine Pokemon. It can just be annoying to deal with in competitive battle. Well unless you have a really strong Choice Banded fighting type or something along the lines of that...

It surprisingly made its way into Smash Bros. I was really surprised that a Pokémon with a creepy stare would make it. - aarond9010

Every. Single. Stinking. Pokemon. That I ran into on the water route of SoulSilver was one of these awful, annoying, weak, and hideous jerks.

Tentacool is basically the zubat of the seas. He is EVERYWHERE!

Trying to get to Emerald City? Too bad Snorlax is taking a nap so forget about it.

Never understood why you couldn't climb over or something

38Emolga

I hate it so much! On Pokemon black and white I spent ages training up a Sandile and then it turned out that Electra had TWO Emolgas. None of my ground type moves worked, and it would damage my Pokemon loads and then switch out with Volt Switch. It took me way too long to beat her. NO electric type should ever be a flying type, and Emolga is just ANOTHER Pikachu clone.
